The TPA2050D4EVM can be evaluated in a stand-alone mode or when connected to existing circuits with
I

C controls.

A desktop or laptop with Windows™ XP installed is required in the stand-alone operation. Connect the
EVM to a computer with a USB cable. A jumper allows the TPA2050D4 to receive power from either the
USB or an external supply via banana plugs. The inputs accept standard RCA plugs. The speaker output
connection accepts banana plugs. The headphone output connection accepts standard 3.5-mm
headphone plugs.

1. Insert the CD provided.
2. Unzip the files to a temporary folder.
3. Install TPA2050D4 software by executing setup.exe located in

TPA2050D4 Setup

.

Accept license agreement and defaults, and complete installation. Note: you can uninstall later with
Add/Remove Programs. It is unnecessary to repeat the preceding steps, once the software is installed.

1. Configure the jumpers as the following table for a default setting:
